Not as many physics tweets as some people expect. Former drummer & DJ. I like to know where my next three meals are coming from. More re-tweets than tweets.

If you ask it a question on an unpopular science topic it learns from the ArXiV and sounds like a confused grad student, but if you ask it about a popular one it sounds like a Redditor confidently asserting to another Redditor that FTL is possible because of the Casimir effect

My belief that Leeds and the North is full of skills and great people and what's holding us back is bad transport opinion has intensified beyond its already extreme position. Anyways, about five teams are working on my bus challenge.

Most common 4-digit PIN numbers - from an analysis of 3.4m leaked from several #databreaches by the late great @‌DataGenetics informationisbeautiful.net/v…
A heatmap reveals the most common 4 digit PIN numbers, visualised from the data leaked from several large data breaches. The horizontal axis plots the frequency of the first two digits, the vertical axis the second two digits. Clear (and somewhat predictable) patterns emerge from the dataset. A diagonal line of ‘heat’ from bottom left to top right reveals people choosing double digits (2323, 6868 etc). A strong horizontal line at the 19 point shows people using their birth year as a PIN code (1971, 1998 etc). And a large amount of heat in the bottom left shows how people commonly use their birthdate in a MM/DD or DD/MM format. The most common code in the set is 1234.

I think we can all agree that the main message from today's selloff is that we've systematically underinvested in urban rail transit in the Leeds area

The most important plot for understanding UK politics & economics now - the collapse in productivity growth since the mid-2000s. Nothing that governments of last 15 years have done has made a material difference, & if we continue doing the same things we'll get the same result.

I believe in better. I think we know a lot of what we need to do. I don't think it's that hard.

Someone just said "the data are". Half the audience sighs. The deepest divide in anglophone statistics. Could get scrappy in here.

In 1971, Leon Chua predicted the existence of the memristor, short for "memory resistor." This unique component, posited as the fourth passive electronic element alongside the resistor, capacitor, and inductor, regulates electrical current based on its history, retaining a "memory" of past charge flow. Fast-forward to 2008: engineers at HP Labs detected an unusual signal. After a great deal of investigation and debate, they determined that this signal was evidence of the memristor Chua had theorized. The prediction of the memristor is rooted in the relationships among voltage, charge, current, and flux, which are clearly illustrated in the subsequent diagram.

For those who celebrate, November 7 is the birthday of two scientific giants: Marie Curie (1867-1934) and Lise Meitner (1878-1968), justly renowned for their world-changing investigations of radioactivity and nuclear fission.

The thing about "the UK’s tax burden is now at a record high", is that this is also true for almost all countries 📈
